Olive Snails - Lettered Olive Snail Oliva sayana

[Avgou]

I was reading on wetwebmedia that olive snails specifically "Lettered Olive Snail Oliva sayana" are predatory and thrive on mollusks...

I've lost 2 Maximas in two months time, each one within 5 days of owning them and they were perfectly healthy the day before.

My clams are pretty much dragged in the sandbed...

Could these guys be the culprits?

i guess it's possible but there are many clam predators / reasons a clam might die, so it would be impossible to say with a lot more info and some pics.

do you even have olive snails in your tank??

Yes I do. I have 4 of these monsters in my tank...Time to purge...

Sorry about your clams. And yes, Olives are extremely capable killers, and they usually kill by engulfing and taking their prey down into the sand, then suffocating it before they eat it. If your clams were small, and it looked like something tried to pull them down into the sand, it was almost certainly the Olives. Olives are very cool snails, but I wouldn't try to keep them in a tank with any other molluscs that I didn't want them to potentially eat.

Cheers,

i thought you were fishing blindly for a culprit, i didn't suspect you had some in your tank.


good luck with the purge

Thanks a bunch Don, I probably could have avoided this if I put them either on rock work or in a Container in the sand bed...but then again they'd probably still get predated...

It's interesting that I have about 5 or 6 decent size clams that were on my live rock that aren't harmed, I've never seen the olive snails anywhere but in the sand bed.
